SVAI Codes
Codes 7E or other than 00 Appear
SVAI CP Codes
These appear during POST. Most are not errors, and will scroll
right on by. Any errors will be preceeded and followed by a "EE"

Turn key to MAINT MODE. The error codes will scroll through
the display. Note the codes for later reference. For a description, go
to the SVAI CP MM table.
SVAI Stops with a Code other Than 7E or 00
Note the error code.

Codes
If an error occurs during system operation, you will get
a checkpoint code as follows:
CP |
Description |
Recommended Action |
C0 |
I/O Channel Check |
Power Off then On. If C0 appears, have system serviced. |
C1 |
Temperature Check |
System is overheated.Check filters. |
C2 |
Power Supply Check |
Low voltage on DC backup connector, battery or fan failure. |
C3 |
ECC Multibit Check |
Power Off then On. If C3 appears, have system serviced. |
C4 |
AC Power Check |
Momentary AC failure. Normal ops will continue. |
C5 |
Watchdog Timer Timeout |
Power Off then On. If C5 appears, have system serviced. |
C6 |
Arbitration Timeout |
Power Off then On. If C6 appears, have system serviced. |
